Application and .August so, les?.` serial No. 216,447.

This inventionrelates to improvements in embossing machines, :particularly adapted tor embossing and the like.`

An'object ot this invention "to provide` an embossing apparatus ,which may beeasaly and inexpensively adjusted ,tothe ordinary brickpextrusion machine. 'Ihe apparatus may be conveniently mounted :onfthe front plate of the extrusion "machine whiclrmay or may not be a part ofthe die .through `which ythe brick material -is extruded.

.A further object `of Athis-ilivention is to provide anelnbossing apparatus` which may bereadily attached to an extrusionmachlne ofthe common type and operated from any suitable source. For instance, it 4may be operated. `from. aprinle `mover .in such ,a manner `that the speed of ftheemboss-ingapparatns becomesdependelfit `upon the speed ot the movfng `clay column as it passes through thefextrusionmachine. i

Another object oat this `invention listo., provide `means# in` the embossing apparatus whereby a change lof embossingdesign may be.niade when `desired by simply` altering the strokeot the actuating means and the embossing elements, thereby providing `a device which, if` desired, may operate immediately under the surfaces of the `brick ma-` terial. Other objects of this invention will appear yfrom the following detailed description of the device and as disclosed in the two sheets of drawings herewith made -a part of this application. l

. in` the embodiment of `the invention herewzith described, Land claimed, numeral l` designates `the front orlproducing end of an extnusioninachine of ordinary make, or other suitable` device, tioncould be practically applied. The mov'- ing -clay column from which the brick is manufactured is `adapted to be forced under pressure through a die plate 2 and opening t The Vplate `2 may `be fastened by any suitable lne-ans such as machine screws 4to the trout endot the extrusion machine 1.passing through suitably formed flange portions integrally or otherwise connected to thejextrusion machine element l.

"The `apparatus for embossing the brick formed `by the extrusion machine may `he mounted, as disclosed in Figuresl and 2 upon the die plate2, however, the particular position of mounting the embossing apparatusuponthe machine has no essential bearing upon the merits ofthecase'inasmuch as the `device lnay be suitably connected with the extrusion machine in any other manner provided it would function properly. For instance, the plate holding the embossing apparatus in operative relationship does not have tube the die plate, although this is the form ot' attachment disclosed in Figures 1 and 2 wherein the device is mounted on the plate 2 in front of the machine element 1 in `such `a manner that the `iour rocker arms `o, 7, 8 and 9are pivotally arranged upon the plate 2 as at 10, 11, 12 and 13, the rocker arms-being suitably spaced from the plate` 2.by means of washer elements 14 in order to allow forthe freedom of `movement of the rocker arms. Itis preferred in this inventionto form `the rocker arms in such a. nia-nner that they may be operated from a common source of power. In order to accomplish this result, rockerarm extensions 7, 15 and .16 are pivo-ted at 11; 8, 17 and 18 at 12,16, `19 and 20at 10; and 9, 21 and 22 at 13, .while pivoted to the rocker arm `elementsl, 18, 19am] 21 are linkportions 23 and 24, and pivot-ally connected to the rocker arm portions 20 and 22 is a conto which this invenl necting rod lilik element 25. A crank ele-` l ment `28 is pivotally `or adjustably connected. to rocker arms 22, and, as at `26, to `anqactuelement 27,.` which maybe op enated by f any available source of power `5 `,for

instance, the crank element 27 could be operated from a source, the speed of which is dependent upon the s eed of the moving clay column as it passes t 'ough the die 3. The length of the stroke given to the rocker arms may be varied or regulated by merely changing the crank pin element 28 to connect with the various positions of the pins 29, 30 and 31, it being understood that an unlimited number of strokes or pins may be used Without affecting the merits of the invention. At the free ends of the rocker arm elements 6, 7, 8,9, 15 and 17 are located segmental portions integrally or otherwise connected with the rocker arms 32, 33, 34 and 35, adapted to be suitably grooved for receiving the embossing members 36, 37 and 38 which may be made oi any suitable material such as a single plain wire, or two or more wires twisted, or may be made of various shapes such as flats, squares, triangular, hexagonal, straight or twisted. Ii' desired, any of these types could be fitted with various shaped bars, lugs or the likefdepending on the nature of the embossing surface sought. Obviously, the embossing elements may be made of any material adapted to be held in operative relationship in the rocker arms for the purpose of embossing the building material, such as brick.

vIn order to securely hold the embossing members 36, 37 and 38 in operative relationship, one end of each embossing member is adapted to be securely held as at 39 and 40 in the segmental portions 41 and 42, and as at 43 in the segmental portion 33. The free ends of the embossing elements 36, 37 and 38 are extended loosely over the cooperating segmental portions 32, 34 and 35 and brought under adjustable tension by means olf holding elements 44, 45 and 46 which are adapted to be threaded at one end and extended through the arm portions 16, 2O and 22 in such a manner that the embossing members may be brought under adjustable tension over the segmental portions by means of adjusting nuts 47.

In order to provide lfor the proper guiding and adjustment of the embossing elements 36, 37 and 38, lug portions 48 are adapted to extend over the plate 2 for receiving adjusting screws 49 which are adapted to cooperate with a member 50 slidably positioned upon the plate 2. A guiding roll 51 is rotatably mounted in the sliding member 5() by means of a bolt element 52 or any other suitable device, the guiding roll 51 to be so positioned within the sliding element 50 that the embossing members may be guided either on the inner or outer side thereof. A plurality of adjusting and guiding devices, as disclosed in Figure 4, are preferably positioned for the purposes of this invention as disclosed in Figure l on the plate element 2, although it is to be understood ing materials and the like.- The that the number and arrangement of the guidin and adjusting elements has no effect upon die merits of the invention, that is, a Isulicient number of the adjusting elements should be used in order to obtain efficient adjustment, when desired, of the embossin portions 36, 37 and `38 for producing a bric as disclosed in Figure 6, having an embossed design 53 thereon` Y In operation, this inventionI provides an apparatus lfor embossing brick, cla build- 'evice 1n general is mounted on a plate which may or may not be a part of the die of an extrusion machine. yThe drawings disclose it mounted on the front of the. machine as clearly shown in dotted lines at 54 in Figure l. The device as described and claimed herewith is extremely simple, eicient and inexpensive, comprising, primarily, four rocker arms or quadrants pivot-ally mounted on the plate. These quadrants are connected and actuated byu rod driven from a crank element or anyother suitable de-J vice. The crank may be olrated from 'any proper type of motor, alt ough it isV vpreferred to operate it'rom some source having a speed which is dependent upon the speed of the extrusion machine and the moving clay column `being extruded therefrom.

`The length of the stroke of the embossing members which are connected with the rocker arm quadrants can easily be regulated by changin the stroke of the crank pin or. by some `ot er suitable means such as the use of various shaped cams in connection with springs whereby it would be possible to operate an almost unlimited change in the pat-- tern ofthe embossing. By utilizing the means just described, the pattern may be varied materially from the ordinary zigzag lines on the face of the bar of clay. For instance, at least four changes may be obtained, such as a vertical line when the twistedwires are at rest, a'short diagonal.

line when a short movementof the wire occurs, and a long diagonal line when the movement is longer, while a curved line wouldrcsult from a varying speed. These curved lines could be madefshort long or medium, the same as the others. lhe pitch: of the diagonal and 'curved line would, of course, be varied by the speed of the `clay column and the movement of the Wire vembossin elements.

In t e invention herewith described, the embossing members may operateon the surface or immediately below the surface of the bar of clay. as desired. In the latter case, the peeling` if allowed to crinkle as l exposing the full e surface. These l embossing lmembers may be made as above described in any suitable materials, and are attached to the faces of the rocker arms or quadrants in sucha manner that any desired tension may be secured. The segmental portions are grooved in orderto properly guide and hold thel embossing members in operative relationship. VProper lateral adjustments may be easily made by means of the adjusting and guiding elements located where neet ed for eiiicient operation on the plate of the apparatus.

The embossing device, according to this invention, does not necessarily have to be it may be cut into bricks and each brick em` bossed afterwards. j y
